Drafted in the 3rd round (93rd overall) by the Seattle Mariners in 2017 (signed for $125,000)

Mills was an outstanding performer for four years out of Gonzaga's bullpen. He's a sidearmer with impressive velocity--his fastball reaches 94-95--and the potential for an average slider. He struck out 58 and walked only four batters during his senior year, racking up 12 saves and posting a 1.79 ERA.
